This invention aims to provide a mechanical movement for operating a signal on a vehicle, the'signal being so actuated and constructed that a person within a closed car may use it to indicate when a left turn is to be made. It is withinthe province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will apepar as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction, it being under-stood that changes may be made in the precise embodiment of the invention, within the scopeof What is claimed, without departing from the spirit'of the invention. In the accompanying drawings:

' Figure 1 shows in elevation a part of an automobile doorwhereunto the device forming the subject matter of this application has been applied,-a part of the lining of the door having been removed, in order that certain working parts may be more clearly shown;

Figure 5 is an elevation showing the lever raised from the position of Figure 3;

Figure 6 is a section on the line 66 of Figure 5 Figure 7 is a section taken above one of the bearing brackets;

Figure 8 is a sectional view illustrating means whereby the spiral or screw is connected to the staff which carries the signal;

Figure 9 is a fragmental sectional view illustrating the joint between the signal stafi and the screw or spiral;

Figure 10 is an elevation showing a ball and socket joint used as a connection between certain parts of the machine.

The numeral 1 marks a support, which may be the front left hand door of an automobile, and inthe door 1 there is a shoulder opening is journaled.

or slot 2 through which the pane?) of glass slides up and down; i i i I Within the support ordoor 1 is'mounted a frame comprising an upright 41; and a cross piece 5, the parts 4 and 5 being made of wood, if desired. The numeral 6 designates a lever fulcrumed atone end, as shown at 7 onlthe cross piece 5. The opposite or free extremity of the lever 6'is reduced, as shown at 8; .7

A two-part bearing 9 is secured to the cross piece 5, and in the bearing 9 the reduced neck 10 (Figure 6) of a shaft ll is journaled. An ofiset bearing bracket 12is attached to the cross piece 5, and in the bracket the shaft 11 is j ournaled, in spaced relation to the bearing 9. The shaft 11 has a squared end 14 on which a cooperating member or' handle 16 is heldby a screw 15. V

The numeral 17 marks an arm which is held by side plates 18 on the shaft 11, so that when the shaft is rotated by means of the handle 16, swinging movement will be imparted to the arm 17. 1 o

Fork pieces 19 are secured to the upper end of the arm 17and carry a shaft 20 oniwhich an antifriction element, such as a roller 21, An inverted U-shaped yoke 22 is provided and the arms and the yoke 22 .are pivotally mounted on the shaft 20 between the fork pieces 19, the roller 21 extend ing into the yoke '22, as Figure 6 will show. The lever 6 slides through the yoke 22 in edge contact with the roller 21.

' An upper'bearing 23 and-a'lower; bearing 24 are secured to the upright' i. In the horizontal portions of the bearings 23 and 2 k (Figure 7) there isa circular opening25-having oppositely=disposed extensions 26. a A sig nal staff 27 is journaled for rotation'in the opening 25 of the upper bearing 23. and car ries an arm 28 on which a signal 28a, of any desired kind, is marked; The arm 28 "preferably is made of stiff wire, to cut down'any resistance when theuarm sticks out from the car at right angles to theline of advance of the car. There is a slot 29 in the lower end of the stafi 27 and into the slot 29 extends a strip 30. A'nut 31 is'threaded on thelower end of the staff 27 and has oppositely-dis posed seats '32, "adapted to receive reduced PATENT oFr cn ffingers 33 on the upper end of the strip 30, the fingers 33 being welded in the seats 32, if so desired, a strong union between the strip 30 and the staff 27 being provided. The strip 30 slides in the extensions 26 of the opening 25 in the lower bearing 24. The extensions 26 of the upper bearing 23 have no function, andioned, and the strip 30, therefore, may be referred to as a screw. The lower end or the strip 30 is connected..(Figure'10,) by a ball and socket joint 35 with the lever. 6, the ball onthe. joint 35 having a small ear 36which isprovided with an opening37. wherein the reduced end; 8- ofthe lever 6 is received.

The; operator swings the handle 16, there? by'rotating the shaft 11, the arm 17 being swungfronr the solid line position of Figure l to the dotted-line position of that figure,the yoke 22 pivoting on the shaft 20, the yoke sliding along the lever, 6 with the roller 21 in contact with the. lower edge of, the lever. The endc8' of the lever 6 raises the strip 30, and thestrip30 raises the staff 27, the signal arm. 28 being lifted out of the. slot 2. The signal arm 28 is lifted rapidly and'then is turnedslowly until it standsout at right angles to the side of the car, the rotation of the stafl27 and of the strip'SO being brought about as. the spiral portion or screw 34 of the strip30 passes through the reduced parts 2610f the opening in the lower bearing 24, the ball and socket joint 35 permitting the strip 30 to rotate withrespect tothe ear 36 which is engaged at 37 with the reduced end 8 of the lever 6.

The operation ofrestoringthe parts to the solid line position of. Figure 1 involves-simply a reversal of the operation hereinbefore described, and need not be dilated upon. For convenience, in claiming the invention, the

staif27 and the strip 30 may be described as a shaft supported for rotation and having a spiral part 34 which cooperates with the bearing 24 to impart rotationtotheshaft, itbe: ing noted that the staff 27 has a longitudinal movement and a rotary movement inthe bearing 23, the strip 30 having a longitudinal movement and a rotary movement in the bearing 24. v

I: claim: v

1. Ina mechanical movement, upper and lower bearings, a staff mounted to rotate and to slide longitudinally in. the upper bearing, a strip mounted to slide longitudinally in the lower bearing, the strip and the lower bearing having elementswhich cooperate to impart rotation to the strip when the strip is moved longitudinally, means under the controlvof an operator for moving the strip longitudinally, and a nut threaded on the stafi and having seats in its edge, the staff being provided in its end with a slot receiving one terminal of the strip, the strip having fingers received in the seat of the nut.

2. In a mechanical movement, a bearing, a shaft mounted to rotate and to slide longitudinally in the bearing, the shaft and the bearing having elements which co-operate to impart rotation to the shaft when the shaft is moved longitudinally, a lever, a fulcrum for one end of the lever, means for pivotally connecting the opposite end of the lever with the shaft to impart longitudinal movement to the shaft, a second shaft, means for journalling. the second shaft below the lever, an arm secured to thesecond shaft and located immediately below the lever, whereby that portion of the arm which is mounted on the second shaft will serve as a stop limiting the downward movement of the lever, and mechanism for. connecting the arm slidably and pivotally with the lever.

3. In a mechanical movement, a bearing, a shaft mounted to rotate and to' slide lone gitudinally in the bearing, the shaft and the bearing having elements which cooperate to impart rotation to the shaft when the shaft is moved longitudinally, a lever, a fulcrum for one end of the lever, means for pivotally connecting the opposite end of. the lever with t the shaft to impart longitudinal movement to the shaft, a second shaft, meansfor journal ling the second shaft below the lever, an arm secured'tothe second shaft and located; immediately below the lever, whereby that portion of the arm which is mounted on the sec- 0nd shaft will serve as a stop limiting the downward movement of the lever, and mechanism for connecting the arm slidably and pivotally with the lever,said mechanism com-. prising a. U-shaped yoke, a pivot element connecting the yoke to the arm, and an anti-v friction member journaled on the pivot element within the yoke, the lever being. slidable through the yoke in. contact with. the anti-friction member.

In testimony'that I claim the foregoing as myown, Ihave hereto affixed my signature.
